Agree with @paul-rogers, we should consider catching exception at a higher
level and provide user general explanation and suggest to refer to the logs,
meanwhile in logs do operator dump (including as much info as possible, like
file name, line, exception etc).

> Convert IndexOutOfBounds exception to UserException with context data where
> possible
> ------------------------------------------------------------------------------------
>
> Key: DRILL-6724
> URL: https://issues.apache.org/jira/browse/DRILL-6724
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.14.0
> Reporter: Bohdan Kazydub
> Assignee: Bohdan Kazydub
> Priority: Major
> Fix For: 1.15.0
>
>
> Sometimes when IndexOutOfBoundsException is exposed to users it is not clear
> what causes the problem. Instead this exception may be converted to a more
> useful UserException containing context data like filename, line, position
> etc (depending on what is available from a reader for a given type).
> A possible approach is to add a method to a RecordReader interface which
> produces UserException of type ErrorType.DATA_READ with context data, so that
> when such an UserException is needed it can be easily obtained by invoking
> the method.
